Blender to Poser 10 issue
When exporting hard surface models from Blender to other formats it's almost always the case that you get "weird" shading or even distortions due to smoothing. 

One method to prevent that is using "Auto-Smooth Normals" in the Object Data panel. 

The two pictures show the same model in Blender and in FBX Review, the first one without "Auto-Smooth Normals", the second one got exported with this option activated.
